ENVELOP FOR SAMPLES.

To all whom 2'25 may concern Be it known that 1, Lion PLANOI-IE, a citizen of the Republic of France, residing at 130 Rue du Faubourg St.-Denis, Paris, in the Republic of France, manufacturer, have invented certain new and useful Improvements in Envelops for Samples, of which the following is a specification.

This invention relates to wrappers in the form of an envelop and the closure of which is obtained by means of a tongue which is secured on the lower part of the envelop and which is slid int-o openings provided on the one hand in the movable flap and on the other hand in the lower part of the envelop.

Hitherto closure or fastening devices of this kind have not gone into practical use by reason of their great disadvantages; in particular, the successive insertion of the tongue inward into the slit in the movable flap, then outward into the slit in the lower part of the envelop was somewhat diflicult and could not be accomplished with the desired rapidity; furthermore, the tongue easily came out of the slits under the influence of an upward pull on the movable flap, so that the envelop was liable to open during handling operations. Again, the card-board fastening members were pasted onto the outside of the envelop so that they were liable to come in contact with outer objects and to be torn off; they were also in full View and gave an unsightly look to the envelop.

According to this invention such disadvantages are avoided in that the openings through which the tongue is passed are located in front of one another and the tongue, which is secured on the lower part of the envelop, can be inserted at a single inward stroke. The insertion of the tongue is therefore more easily and quickly done; on the other hand, an upward pull 011 the movable flap has no tendency to withdraw the tongue from the openings where it is engaged so that the closure or fastening is safe. Again, the fastening members can be easily past-ed to the inside of the envelop so that there is only the tongue at the outside; the liability to come in contact with other objects and to be torn off is thus done away with and the envelop presents a nice appearance.

One embodiment of this invention is Specification of Letters Patent.

shown, by way of example, in the accompanying drawings, in which:

Figures 1 and 2 are part elevations of the envelop open and closed. Figs. 3 and A are part vertical sectional views of the same envelop open and closed.

a designates the lower part of the envelop and Z) the movable closing flap. In the parta are provided the slits 1 through which is passed a piece of card-board 2, pasted at its edges onto the inner face of the envelop. Such piece has at its lower edge a tongue 0 which is placed outside the envelop furthermore, a horizontal slot (Z is made therein to receive the tongue 0 on the latter being bent upward. Another piece of card-board 3 is pasted to the flap 7) on the inner face of the latter and an opening 6 is cut in the flap and cardboard in order to provide at the edge of the piece 3 a transverse brace f. When the envelop is being closed, the opening 6 comes in front of or opposite to the slot 4, and the brace f comes between the slot (Z and the base portion of the tongue 0. The tongue is then bent upward over the brace f and is caused to pass at a single stroke through the opening 6 and the slot cl. The brace f is thus completely confined by the tongue 0. The height of the opening 0 is preferably such that on the envelop being closed, the tip of the upwardly bent tongue comes within the contour of such opening as shown in Figs. 2 and 3. Such arrangement prevents the tongue 0 from being in serted inadvertently directly into the opening 6 without passing through the slot (Z, as then it would be clearly seen that the closure had not taken place. Again, the tip of the tongue lies embedded in the opening 6 and does not run the risk of coming in contact with objects outside.

A little tongue 9 is formed in the tongue 0 by slitting the latter, the tongue 9 being so arranged that its free end lies near the base of the tongue 0. The tongue 9 serves to facilitate the opening of the envelop by allowing the tongue 0 to be easily disengaged from the opening 6 and the slot (Z; it also serves to facilitate the entry of the tongue 0. Furthermore, in case the envelop is designed to be carried by hand, it is advantageous to form as an integral part of the piece of card-board 3 a strip 72. which is bent in the shape of a loop, such loop extending outward through a slot 4 in the upper edge of the envelop. Into such loop a finger can be passed to comfortably carry the envelop.

l or envelops intended to be sent by mail, the loop It Will generally be dispensed With.

Claim:

The combination With an envelop having the back of its body provided with spaced slits, of a piece of cardboard having side members engaged in said slits and secured to the inner face of the said back of the envelop body, the said piece of card-board having a tongue projecting downward from its lower portion and extending outside of the envelop body, the said piece having a transverse slot above the base of the tongue,

the portion of the said piece above the slot forming a transverse bar, the flap of the envelop being provided With an opening adjacent its edge, the said bar and the said slot of the piece being exposed through the said opening in the flap When the latter is closed, the said tongue being adapted to be bent upward over the edge of the flap and inserted directly through the opening in the flap and the slot in said piece and under the said bar of the piece.

In testimony, that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
